Getting the "Apple could not verify this app is free of malware" error on macOS? Learn 3 quick ways to bypass Gatekeeper and open blocked Mac apps safely.
We’ve all been there. You download a perfectly safe, trusted app from a developer’s website, try to open it, and macOS immediately throws a security tantrum.
The dreaded popup reads: "[App Name] Not Opened. Apple could not verify this app is free of malware..."
This is macOS Gatekeeper doing its job a little too well. If you’re 100% sure the app is safe, you don't need to throw it in the trash. Here is how to override the block and launch your app in seconds.
Method 1: Override via System Settings
If the shortcut doesn't work, you can manually grant permission through your Mac's security settings.
- Click the Apple logo in the top left and open System Settings.
- Navigate to Privacy & Security in the left sidebar.
- Scroll down to the Security section.
- You will see a notification stating your app was blocked. Click the Open Anyway button.
- Enter your Mac login password or use Touch ID to confirm.
Method 2: The Terminal Nuclear Option (For Stubborn Apps)
If the app still refuses to open, macOS may have aggressively quarantined the file. You can strip the quarantine flag using a simple Terminal command.
- Open the Terminal app (Press
Cmd + Spaceand search for Terminal). - Copy and paste the following command, adding a space at the very end:
sudo xattr -rd com.apple.quarantine
- Drag and drop the blocked app icon from your Applications folder directly into the Terminal window (this automatically inputs the exact file path).
- Hit Enter, type your Mac's admin password (no characters will show, just type and hit Enter), and try opening the app again.
Method 3: The Right-Click Shortcut (Fastest Fix)
The absolute quickest way to bypass the macOS unidentified developer block is the secret right-click trick.
- Open Finder and go to your Applications folder.
- Locate the blocked app.
-
Right-click (or hold
Controland click) the app icon, then select Open from the menu. - A new dialogue box will appear, but this time, it will include an Open button. Click it, and macOS will permanently whitelist the app.
⚠️ A Quick Safety Reminder: macOS Gatekeeper exists to protect your system. Only use these bypass methods if you downloaded the app from an official, trusted source. If you aren't sure where the app came from, it’s safer to delete it.
